DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch device used for controlling the position of an electric seat in an automobile or the like.
In particular, the present invention relates to a switch device in which an actuator of a switch main body provided in a case and an operation knob provided outside the case are interlocked and connected via a slider mounted through the case.

[0002]

2. Description of the Related Art As disclosed in Japanese Utility Model Publication No. 1-15757, for example, a switch body, a slider for operating the switch body, a neutral return mechanism, etc., other than an operation knob, are all provided in a case. Related components are incorporated, and a shaft protruding from a slider is projected outside a case, and an operation knob is fitted and connected to the shaft.

[0003]

However, in the above-mentioned conventional device, when different types of switch bodies are used as built-in switch bodies in different types of switch devices, the same case is used because the switch bodies have different heights. When using and using a slider of the same configuration, the slider and the actuator of the built-in switch cannot be linked and connected, and therefore, different forms for each switch device, that is,
Cases having different height dimensions had to be manufactured and used. Further, it is conceivable to change the slider structure, but in that case, the operation knob and the like must be changed accordingly. As a result, the manufacturing efficiency was poor, resulting in an increase in product cost.

It is an object of the present invention to increase the manufacturing efficiency and reduce the cost by making it possible to share a case when manufacturing a switch device of a different model in which a built-in switch body is different.

[0005]

In order to achieve the above object, the present invention has the following arrangement.

[0006] An actuator of a switch body housed in a case and an operation knob arranged outside the case are
A switch device interlocked and connected via a slider mounted through a case, wherein the slider is formed from an external slider disposed outside the case and an internal slider disposed inside the case. The external slider and the internal slider
The engaging hole and the engaging claw that engage and connect by engaging
Each of the engaging claws is formed through an operation hole of the case.
The external slide by engaging the
And the internal slider is engaged and connected, the operation knob is connected to the external slider, and the actuator of the switch body is connected to the internal slider.

[0007]

When manufacturing various types of switch devices incorporating different switch bodies, only the internal slider can be made different depending on the height of the switch body. Thereby, the case is shared.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a switch device used for controlling the position of an electric seat in an automobile will be described with reference to the drawings.

[0009] As shown in FIG.
An operation knob 2 for adjusting the angle of the seat backrest and an operation knob 3 for adjusting the height of the seat, the front-rear position, and the vertical angle of the seat seating portion are provided on the upper surface of the horizontally long case 1. It is configured.

A printed circuit board 4 is screwed together with the cover case 5 inside the case 1. A switch body S 1 operated by the operation knob 2 is mounted on an upper surface of the printed circuit board 4. Three switch bodies S2, S3, S4 operated by the knob 3 are mounted. The switch bodies S1, S2, S3, and S4 are of the same specification equipped with an actuator 6 that slides along the upper surface thereof.
And S3 actuator 6 can slide left and right,
The actuators 6 of the switch bodies S2 and S4
Are mounted so as to be slidable back and forth, and operation knobs 2 and 3 corresponding to each actuator 6 are interlocked and connected via a slider 7.

The slider 7 includes an internal slider 7a provided inside the case 1 and engaged with a projection 6a on the upper surface of the actuator 6, and an external slider 7b provided outside the case 1, and the slider 7 is A pair of connecting legs 7c provided in a row are inserted into the case 1 through a pair of elongated operation holes 8 formed in the case 1, and the connecting legs 7c are formed.
By engaging the engaging claw 7e formed on the inner slider 7a with the connecting hole 7d formed on the inner slider 7a, the inner slider 7a and the outer slider 7b are connected with the case 1 sandwiched therebetween, and the entire slider 7 is operated. The case 1 is slidably displaceable along the hole 8 and the guide rail 9 on the upper surface of the case 1.

A shaft 7 is provided on the upper surface of the external slider 7b.
A ball 11, which is assembled from below and is urged downward by a spring 10, is formed inside the shaft 7 f in a V-shaped recess formed on the upper surface of the case 1 between the pair of operation holes 8. A neutral return mechanism N which is biased and engaged with the input cam 12 and biases and returns the slider 7 to the middle of the operation range (neutral position) by the biasing engagement of the ball 11 with the recessed cam 12. .

On the upper surface of the case 1, one round shaft guide pin 13 for supporting the operation knob 2 so as to be able to swing right and left, and two for supporting the operation knob 3 so as to be able to move right and left linearly and swing back and forth. Square shaft guide pins 14 and 15 are erected.
The structure for assembling the operation knobs 2 and 3 to the respective guide pins 13, 14 and 15, and the structure for interlocking the operation knobs 2 and 3 with the sliders 7 will be described below.

A round guide pin 13 is provided on the lower surface of the operation knob 2.
And a long fitting hole 17 formed before and after fitting to the shaft 7f of the slider 7, and the operation knob 2 is swung right and left around the axis P1 of the round guide pin 13. By the movement operation, the slider 7 connected to the shaft body 7f via the fitting hole 17 slides left and right, and the actuator 6 of the switch body S1 is slid left and right. The annular projection 18 formed on the outer periphery of the shaft body 7f and the annular projection 19 formed on the outer periphery of the round shaft guide pin 13 press-fit into the grooves formed in the fitting hole 17 and the support hole 16, and the operation knob 2 are supported so as not to come off.

The lower surface of the operation knob 3 has a square axis guide pin 1
Cross-shaped guide grooves 20 and 21 for allowing relative movement of front and rear, left and right, and shafts 7 of left and right sliders 7 that move back and forth
f, and long fitting holes 24 before and after being fitted to the shaft 7f of the central slider 7 that moves left and right. , 15 and the guide grooves 20, 21, the entire operation knob 3 is linearly operated left and right, so that only the actuator 6 of the central switch body S2 is slid left and right, and the operation knob 3 is moved to the right end shaft 7f. Of the switch body S3 is slid back and forth, and only the actuator 6 of the switch body S3 is slid back and forth.
By operating the operation knob 3 back and forth about the axis P3 of the shaft 7f on the left end, only the actuator 6 of the switch body S4 on the right end is slid back and forth. The annular projection 25 formed on the outer periphery of each shaft 7f
As a result, the operation knob 3 is prevented from coming off as described above. The case 1 is fitted with a rubber dustproof cover 26 which is fitted to and adheres to the bases of the shafts 7f and the square shaft guide pins 14 and 15. Further, a rubber piece 27 for absorbing the looseness between the operation knobs 2 and 3 and the shaft 7f is fitted and attached to the tip of the shaft 7f.

[0016]

According to the present invention, when manufacturing various types of switch devices incorporating different switch bodies, only the internal slider can be made different according to the height of the switch main body. The case can be shared for the manufacture of, and the production equipment and the manufacturing process can be simplified and the cost can be reduced.

In particular, since only the internal slider needs to be changed and the external slider does not need to be changed, the operation knob connected to the slider can be shared and the connecting operation can be easily performed. In this respect, the manufacturing efficiency can be increased and the cost can be reduced. Is effectively promoted.
